| Outline of Final Research Achievements |
Natural-killer group 2 member D (NKG2D), a C-type lectin molecule, is an activating receptor. In human, UL-16 binding protein (ULBP) / retinoic acid early transcript 1 (REAT1) family are known to encode ligands for NKG2D. The human ULBP gene family is composed of six functional members, ULBP1-ULBP6. In the present study, we found that the ULBP4 expression in colon cancer cell lines were inversly correlated with methylation level of the ULBP4 gene, indicating that the difference in methylation pattern may differently contribute to the regulation of NK function. In addition, we identified polymorphisms in ULBP2 and ULBP5 genes from rhesus and crab-eating macaques. It was suggested that the Old World monkeys are good animal models for developping the immune regulation by ULBPs.
